Sigma 23mm f/1.4 DC DN Contemporary Lens (Sony E)

Sigma 23mm f/1.4 DC DN Contemporary Lens (Sony E Mount)
The Sigma 23mm f/1.4 DC DN Contemporary is a fast-aperture wide-angle prime lens tailored exclusively for APS-C format Sony E-mount mirrorless cameras. Delivering a classic 35mm full-frame equivalent focal length, this lens provides the quintessential, universally favored field of view for storytelling. As a premier entry in Sigma’s Global Vision Contemporary line, it masterfully merges elite high-resolution optics and an ultra-bright f/1.4 threshold into a portable, everyday footprint. It serves as the ultimate walkaround choice for street reportage, environmental portraits, travel documentation, and low-light videography.

Cinematic f/1.4 Aperture & Advanced Optical Matrix
Ultra-Bright f/1.4 Maximum Aperture: The fast f/1.4 aperture yields exceptional light-gathering performance in dimly lit interiors or late-night street environments. This threshold gives creators deep control over shallow depth of field, enabling dramatic subject isolation against a soft backdrop.

9-Blade Rounded Diaphragm: Outfitted with a rounded nine-blade aperture structure to deliver smooth, circular out-of-focus highlights and a creamy, natural-looking background blur (bokeh).

13 Elements in 10 Groups: The sophisticated internal optical layout incorporates three SLD (Special Low Dispersion) glass elements and two high-precision aspherical elements. This advanced configuration aggressively minimizes chromatic aberrations, color fringing, and geometric distortions to render crisp, high-contrast imagery.

In-Camera Correction Compatibility: Fully optimized to interface with native Sony camera firmware, supporting automated lens aberration corrections and electronic optical adjustments for vignetting, distortion, and chromatic anomalies straight out of camera.

High-Speed Stepping AF & Macro Capabilities
Rapid Inner Focus Stepping Motor: Driven by an advanced internal stepping motor paired with an inner focusing mechanism. This system achieves rapid, dead-accurate, and near-silent autofocus tracking, matching the rigorous requirements of high-speed portrait photography and quiet, cinematic video capture.

AF Assist Support: Natively compatible with the AF Assist function on supported Sony camera bodies, allowing operators to seamlessly blend automated tracking with smooth manual focus ring overrides on the fly.

Dynamic Close-Up Latitude: Boasts an exceptionally close 9.9-inch minimum focusing distance, allowing photographers to step intimately close to nearby subjects to capture detailed macro textures and uniquely compressed close-up portraits.

Weather-Resistant Build & Durability
Dust & Splash Resistant Construction: Built with comprehensive weather gasketing around the mount interface to block moisture and dust intrusion, providing peace of mind when shooting in unpredictable outdoor climates.

High-Precision Brass Bayonet Mount: Features a solid, treated brass bayonet mount that secures long-term mounting accuracy, structural rigidity, and robust durability over years of constant lens changes.

Included Accessories
Dedicated Lens Hood Included: Ships complete with its original matching plastic lens hood, engineered to block stray, off-axis light from causing internal flare while providing robust physical impact protection to the front element.

Front & Rear Caps Included: Includes both the front and rear lens caps to securely safeguard the glass surfaces from dust, fingerprints, and smudges during transit or storage.
